BRUSH.

SPECIFICATION forming part of Letters Patent No. 329,413, dated October 2'7, 1885.

Application filed January 14, 1885. Serial No. 15-2,?57. (No model.)

To all whom it may concern.-

Be it known that I, EDWARDS W. PORTER, of Detroit, in the county of WVayne and State of Michigan, have invented new and useful Improvements in Brushes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, which forms a part of this specification.

This invention relates to certain new and useful improvements in the construct-ion of brushes, and is especially designed as an improvement upon the patent of March 13, 1883, issued to D. A. McDonel.

Infmanufacturing brushes as described in the aforesaid Letters Patent, wherein the bristies are secured in a longitudinal groove inthe head by means of a retaining-wire, it has been impossible to construct brushes with other than square ends; and it is the object of this invention to embody the construction described in such patent in the construction of brushes with a pointed end and of such shape as is known in the trade as scrubbing-brushes, and to that end the invention consists in the peculiar construction and operation of the parts, all as more fully hereinafter set forth.

In the drawing my improved brush is shown in perspective, with one of the straight rows of bristles partly left out, and with the point also in perspective, but detached, and in which A represents a brush-head wherein are formed the parallel channels a, which are designed to receive the straight rows of bristles. In order to continue the rows of bristles to the point in making a pointed or scrubbing brush, it is necessary to cut away the brush-head, as at b, to receive a detachable plate, B, into which the bristles are stuck in the ordinary manner,

and which is retained in place by a screw or other suitable means.

To build up a brush, the proper quantity of bristles are placed across the channel a and forced tightly into the same by a wire, 0, so that the bend of the bristles is forced into the bottom of the channel. The projecting ends of the wires at the heels of the brush are then turned and driven into the head, being menforced and retained by a staple,which is driven across the bent end of the wire. The opposite and projecting ends of the wires are designed to engage with holes 0 in the edge of the plate B, which has previously been provided with bristles in the ordinary and old manner of constructing brushes. Such plate B being rigidly secured upon the head, it holds the corresponding ends of the wire 0 to place, securing the straight rows of bristles in their respective grooves or channels.

\Vhat I claim as my invention is 1. A pointedended brush having straight rows of bristles secured in grooves by straight wires, substantially as described, and curved rows forming continnations of such straight rows, the curved rows being secured in the ordinary manner in a separate head, which is afterward secured to the main head, substantially as specified.

2. A brushhaving the straight rows of bristles secured in grooves by straight wires, one end of which is secured in the head, and a detachable pointed portion of the head, which, when in place, secures the other end of said wires, substantially as set forth.
